ZRN-100F plug-in ultrasonic flowmeter

ZRN-100F plug-in ultrasonic flowmeter
 

Product description:

ZRN-100F inserted ultrasonic flowmeter is a ZRN-100 series ultrasonic flow meter can be installed plug-meter line. Utilizes low voltage, multi-pulse principle receives the transmission, the use of double-balanced differential signal transmitter and receiver patented technology and hardware-independent design methodology;.. through the selection of the latest international and most advanced large-scale integrated circuits and advanced SMD placement welding process from production to ensure that each factory flowmeters have the same performance flexible full Chinese Display Host (wall F1 standard, explosion-proof wall F2, panel mounted S-type, wall FN network type) to meet a variety of industrial site; Plug-in ultrasonic flowmeter solve Clamp-on ultrasonic flowmeter Long working signal attenuation and the inner surface of the pipe while not receiving a signal scaling problem, do not shut down the installation. Applicable to a variety of line pipe, cast iron, glass, steel, PVC and cement. Measurement host
